Application filed March a,

and the object of my invention is not only to provide a simple and el'liective support for the rolls, but to make that support readily insertible for the purpose of mounting the rolls when assembling the machine and as readily removable for disconnecting them for any purpose desired.

Referring to the drawings in which similar numerals indicate identical parts- Figure 1 is a rear view of a portion of the upper end of a harvester and binder elevator lrame including my improvements.

Fig. 2 is a section on the line 2-2 of Fig. 1 with gears, sprocket and chain in place.

Fig. 3 is a view similar to Fig. 1 but with the detachable parts of my improvement re moved.

Fig. l is a section on the line 4L-d of Fig. 1, and

Fig. 5 is a side elevation of the removable casting.

Normally, in the construction of the modern harvester, a solid casting is secured to the upper end of the elevator i'rame and the spindles of the rolls are journaled in bearings therein, so that in the event it should be necessary to remove the rolls for any reason whatever the entire casting must be removed, and as other parts oi the harvester are connected to the casting the removal of it means, practically, dismantling that portion of the machine. In the drawingsis shown a casting 1 to which ll secure a side 2 of the elevator frame and alsobinder deck 3 and a strut 4, as commonly employed in machines of this class. I cut out the casting 1 to form openings 5 and 6 of slightly larger diameter than the rolls 7 and 8, shown in full lines in Figs. 2 and 4 and in dotted lines in Fig. 1, and through these openings I insertthe rolls 7 and 8 which are to be supported at their farther ends by the type of specification of Letters Eatent.

bearing ordinarily employed and not shown in the drawings. The opening 6 is extended downwardly, as shown in Fig. 1, for a purpose hereinafter disclosed.

From the grainward side of the opening 5, and for substantially one half the circumference thereof, a flange 9 extends outwardly, and a similar flange 10 extends outwardly from the stubbleward side of the opening 6. After the rolls 7 and 8 are in place I support their rearward ends by a member 11 which is adapted to fit snugly between theflanges 9 and 10 and is rigidly secured to the casting 1 by bolts 12 and 13. The ends of the member 11 are rounded con centrically with the openings 5 and 6 and are provided respectively with bearings 14: and 15 preferably integral therewith. The rolls 7 and 8 are provided respectively with spindles 16 and 17 rigidly fixed in the ends thereof in a well known manner; the spin dle 16 is rotatably journaled in a bushing 18 in the bearing 14, the latter having a notch 19 in which a projection 20, on the bushing 18, is received to hold the bushing against rotary movement. The spindle 17 is rotatably journaled in a bushing 21 in the bearing 15, the bushing 21 being also provided with a projection 22 which extends into a notch 23 in the bearing 15 and holds the bushing 21 against rotation. The spindies 16 and 17 extend a predetermined distance outwardly from their respective bushings and for that distance are threaded to receive gears 24: and 25 respectively, the interior of the hubs thereof being threaded for that purpose.

The member 11 has a downward extension 26 on which there is a stud 27 on which an idler gear 28 is mounted and in mesh with the gears 24: and 25. The stud 27 is bored to form a bearing for a rod 29 having its outer end bent to form a handle 30, and carrying rigidly secured on its inner end an arm 31 to the stubbleward end of which is pivotally connected a tripping bar 32 connected to a clutch, not shown in the drawings, by which the power of the bull wheel of the machine is connected or disconnected to operate the harvester mechanism in a manner well known in the art. The usual sprocket 33, having the interior of its hub threaded, is also mounted on the spindle 16 and is actuated to rotate the roll 7 by a sprocket and chain 34, and as the gears 24:21116'. 25 are in mesh With the idler gear 28 both rolls 24 and '25 are-rotatedin the same direction, this construction is of the type commonly employed in the modern harvester and binder. The parts being assembled as shown in Figs. 2 and l and when it is desired to dis- .connect the rolls for any purpose, the chain 34 is removed and the sprocket 33 and gear 24: are rotated in the direction opposite to their normal direction of rotation until freed fromthe-spindle 16; the gear 25 is freed arm 31 is in a vertical position, the member 11 is readily removable carrying with it the rod 29 and the idler gear 28, thearm 81 passjing freely through the downward extension 'of'the opening 6.

By the means heretofore described I have provided an eminently practical construction in which the frame of'aharvester elevator can be fully assembled before the rolls are mounted, and in which the rolls canbe removed without disconnecting the parts of the elevator frame, a distinctly advantageous feature in machines of this class.

What I claim is- 1. In a harvester and hinder, the combination with the elevator frame, of elevator rolls having spindles, a casting on the frame, openings in said casting through which the rolls are capable of being inserted or withdrawn, a member having bearings in which the spindles are supported, means on the casting to locate said member in place to close said openings, and means to secure the member rigidly to the casting.

2. In a harvester and hinder, the combination with the elevator frame, of elevator rolls having spindles, a casting on the frame, openings in said casting through which the rolls are capable of being inserted or withdrawn, a flange on the grainward side of one of the openings, a similar flange on the stubbleWa-rd side of the second opening, a member adapted tobe located in place by said flanges to close the openings, means to rigidly secure the member on the casting, and hearings on said member in which the spindles are sup orted.
